Hi David,
If you were to add a series resistor this would limit the current available to the MOSFET gate. However, with the DRV8305 we offer a feature called IDRIVE that allows you to vary the source / sink current of the gate driver. For this device gate resistors are often not needed if the IDRIVE settings are acceptable for your application.
Peak current is the maximum source or sink current applied to the MOSFET gate during turn on and turn off transitions. This will control how quickly the external MOSFETs can slew. We have an application note linked below if you're interested in reading more about this:
